How To Remove And Prevent Nasty Mold In Grout

Ewwww who wants to see nasty mold building up on the tile grout in the bathroom? It can be one of the worst things to see in the home, and detrimental to our health. In this post, I’m going to help you to reclaim your sparkly and shiny bathroom by giving you some super tips to remove mold in grout.

Firstly let’s talk about why your bathroom is susceptible to mold in grout.

Mold and mildew spores love damp areas and places where moisture sits. The bathroom is a perfect environment for mold and mildew to grow. They particularly like to cling to the surface of the grout because it’s rough in texture, porous and a perfect surface for the mold and mildew spores to cling to.
The surface of the grout itself is often missed when you wipe over a tiled surface in the bathroom as it is slightly recessed from the tiles.
Around the bathtub, showers and windows are particularly susceptible to mold growth if not enough ventilation is provided to these areas.
